What are the lights for photography?

Lighting is one of the basic elements of image creation. Without good lighting, it is impossible to create a picture that is higher than life and has a strong artistic taste. Commonly used photographic lights include LED constant light, flash light, stick light, panel light, ring light, fluorescent light and so on. Different lights can create different atmospheres. From the perspective of scene layout, lighting can be divided into main light, auxiliary light, ground light and ambient light.

Of course, more often, a single light source is too stiff, so some accessories, such as soft box, radar cover, standard cover, honeycomb cover, beam tube and so on. When taking pictures, it will be placed on the lamp, which can change the range and color of light and make the light soft.

Nowadays, the development of photographic lamps is becoming more and more professional, and many factors need to be considered when choosing them. There are mainly the following points:

I. Power

At present, the main power of normally-lit fill lamps are 100W, 150W, 200W and 300W. If it is an indoor scene fill lamp, you should choose a fill lamp above 150 W ... Add 100W and 150W as needed. Specific facial details and environment rendering can be achieved by considering bar light and panel light.

If it is a private live broadcast or self-media video shooting, you don't need to show the products, just enhance the facial color of the characters to look more beautiful, and it doesn't cost too much. Generally, you can use a fill light with an adjustable color temperature of 100W to illuminate people around, and then use a stick light, a panel light, a pocket light, etc. In order to highlight the facial color, even just put a pocket lamp and a panel lamp in front of the computer to adjust the atmosphere, mainly depending on personal needs.

Second, the color temperature

Color temperature is the degree of color presentation of light, as shown in the following figure, different color temperature ranges can make light present different atmosphere. Color temperature is mainly used to contrast the atmosphere, including people and scenes. By adjusting the color temperature, colors can be changed to present different scenes and feelings.

At present, the fill light is divided into three forms: single color temperature, double color temperature and full color. Single color temperature is not adjustable, and the general parameter is 5600 200 K, while double color temperature can be adjusted cold and warm, generally between 2700 K and 6500 K 200 K. Full color has a wider adjustment range, generally between 2800 K-1000 K 200 K. Generally, the larger the color temperature range, the more scene atmosphere can be presented.

Third, brightness.

When it comes to brightness, many people will think that brightness refers to the power of the lamp. The higher the power, the brighter the headlights. Anyone who has used LED lamps, energy-saving lamps and incandescent lamps will understand that the years of the three lamp areas with the same power are obviously different. LED lights are the brightest, followed by energy-saving lamps and incandescent lamps.

The brightness of the lamp is mainly determined by the luminous flux, that is, the sum of the light emitted by the lamp in unit time. The greater the value, the greater the brightness. His unit is usually expressed in lumens (lm). The greater the lumen value, the brighter the lamp at the same power. However, at present, many brands will not clearly indicate the specific lumen value parameters.

Fourth, the color index

Color index refers to color rendering index (CRI) and television illumination consistency index (TLCI) respectively. Color rendering index refers to the inherent color reduction degree of light to objects and people, which makes the photographed things brighter and more realistic, just like in the sun. The color rendering index of sunlight is 100, and the closer the light is to 100, the smaller the color distortion of the irradiated object will be. The consistency index of TV lighting is based on the picture output by the camera, which is used to describe the color expression ability of lighting. The higher the index, the better the color performance of the light and the more atmospheric the shooting. Generally, these two indicators need to reach more than 95%.

Verb (abbreviation for verb) brand and model

The best fill light lamps are made in Switzerland and Germany, and the prices abroad are very high. If you pursue cost performance, choose domestic brands. At present, domestic brands are more professional, such as Speedmap, Shenniu and love figure. Among them, Speedmap has the highest cost performance due to the integration of R&D, production and sales, but its brand awareness is slightly lower.
